Which Holley ECU Is The Best For You? - 05/18/2022

Hot rodders and gear heads are the true definition of control freaks. In the early years of performance and racing, the focus was entirely on making horsepower. But now making power is much easier. Now the goal is as much about controlling the engine both from how much fuel and spark each cylinder needs along with accurately monitoring every nuance. This can’t be done by analog means with manual gauges and maybe a movie camera like our grandfathers did it. That’s just too cumbersome. Today it takes computer power. - Read More

How To Update Your Outdated ECU To Modern EFI - 06/15/2021

There are probably thousands of small-block Chevys running wild on the streets right now with an antiquated factory TPI system ECU. We’re talking computers with removable chips!

Going In-Depth With Holley's Terminator X Stealth 4500 EFI System - 03/16/2021

Hot on the heels of the Terminator X Stealth 4150 EFI system that debuted earlier this year, Holley has now added the Terminator X Stealth 4500 EFI system to the lineup. As the name implies, the new hardware is designed to work with 4500 flange intake manifolds, but this system is much more than just a carburetor replacement that’s designed to improve drivability and throttle response. - Read More

How Does A Dual Sync Distributor Work And When Do You Need One? - 04/19/2021

Conventional distributors use centrifugal weights and springs to affect the engine timing. Essentially the faster the distributor spins, the more the weights move away from the center of the distributor, and that alters the engine timing in turn.

Although that design worked well enough for decades of automotive applications, it’s not exactly cutting edge tech by today’s standards, and it isn’t particularly user-friendly when it comes to tuning. - Read More

How To Choose The Correct Fuel Injector For Your Engine. - 04/15/2021

When it comes to engine performance, the buck ultimately stops at fueling. After all, if you don’t have enough juice to go with that cool air and hot spark, you’re ultimately selling yourself short. Worse still, a fuel system that can’t keep up with the rest of your setup can ultimately lead to engine damage. And that’s why it’s important to make sure the fuel injectors you’re using are up to the task. - Read More
